WILLIAM J. YOUNG, OF LYNN, MASSACHUSETTS.

COUNTER-MOLDING MACHINE.

To all whom 'it may concern.'

Be it known that I, WILLIAM J. YOUNG, citizen of the United States,residing at Lynn, in the county of Essex and State of irlassachusetts,have invented certain new and useful Improvements in (munter-Yielding'Machines; and I do hereby declare the following' to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the saine.

The present invention relates to machines for manufacturing' boot andshoe counters or stilfeners and more particularly to an improved machinefor molding' or shaping,l counters, such machines beingI generally knownto the trade as counter molding machines.

The object of the present invention is to produce a counter moldingfmachine of simple form and arrangement in which the counter molding diesor molds shall be so constructed and actuated as to apply uniformmolding' and shapingl pressure over the entire surface ofthe counter',and whereby the sh apingi' molds shall be automatically adjustable tovariations in thickness of the material from which the counters aremade.

lo the above end the present invention consists of the devices andcombinations of devices which will be hereinafter described and claimed.

The present invention is illustrated in the accompanying; drawings, inwhich,

Figure 1 shows in top plan view so much of a counter molding' machine aswill be necessary to explain the present invention, the molding dies inthis view beingI closed. Fig'. 2 shows a similar view with the moldingdies open. i

inasmuch as the present invention resides wholly in the form andarrangement of the molding,I dies it has been deemed unnecessary to showor describe the machine Vin detail or the means for reciprocatingl thefemale mold, all of which can be of any usual or preferred construction,such for example like the machine disclosed in Letters Patent of theUnited States #519936 granted to me on the 15th day of May, 1894.

The machine comprises a suitable frame which may be of any usual orpreferred form or arrangement and which supports the bed. 1, said bedbeing' mounted on the frame in an inclined position as shown in thepatent referred to, whereby the molds are disposed in Specification ofLetters Patent.

convenient position for the operator in removing and inserting thecounters.

The male mold 2 may be of any usual or ordinary shape to produce theshape of coun ter desired, and it is supported in a fixed position uponthe base 3 of the bed 1, it being' preferably so supported that it mayto a certain extent yieldv under the action of thel female mold, and forthis purpose it is mounted upon a block f1, the stem. 5 of which isarranged to slide in a bearing 6 formed in the base 3. At the lower endof the stem 5 there is supported a washer 7 which rests upon the innerend of a strong` coiled springI S which is located in a chamber 9 formedin the base 3, the outer end of the springl 8 being' supported by anadjusting plate 10 which is held to the base 3 by means of adjusting;bolts 11, the arrangement being such that the tension of the spring; Smay be adjusted by moving in or out the .late 10.

It wil be noted. that by the construction inst described the male mold 2is capable of having' a slight downward yielding1 motion when acted uponby the female mold. rfhe female mold 12 is of that type known. as asectional or divided mold, and comprises members 13, each of which isformed with a moldingr face corres ponding' in contou r to one half ofthe molding' face of the male molds 2. Each of the sections 13 issupported by an arm 14 which is pivotally connected at 15 to levers16,the levers 16 being pivoted at 17,to the sliding` block or head 1Swhich is arranged to be reciprocated along` a suitable guide way 19formed on the inner faces of the sides of the bed 1, it being movedalong` the guide way by any suitable mechanism, as by means of togglelevers as shown in the patent hereinbefore referred to, a portion of onemember 20 of the toggle levers being shown in the drawings.

The above arrangement is such that a movement of the block 1S along' theguide i.

way 1.9 will impart to the divided mold 12 a movement toward and fromthe male mold 2 as will be clear from an inspection of the drawings. Itis designed that as the divided mold 12 moves downward toward the malemold 2 that said moldv shall be closed in order to impart the necessarymoldingI pressure to the counter, and for this purpose the lower ends ofthe arms 14 which carry the sections 13 of the divided mold are beveledas shown at 21 and preferably provided with hard steel plates 22 whichpreferably extend some distance beyond the lower ends of the arms 14,and these beveled ends, or the plates 22 secured thereto, are arrangedto engage rollers 23 carried by heads 24 supported to slide in bearings25 formed in the casings 26 secured by bolts 27 to the bed 1. The heads24 rest upon coiled springs 2S which are received in chambers 2) formedin the casings 26 and they are provided with rods 30 which pass throughopenings 31 in the ends of the chambers, and the outer ends thereof arethreaded to receive the adjusting stop nuts 32, which nuts engage theouter surfaces of the casings 26 and limit the inward movement of theheads 24, at the same time permitting the adjustment of the tension ofthe springs 2S.

It will be noted. that upon a downward movement of the block 18, theplates 22 of the arms 14 will contact with the rollers 23 supported bythe heads 24, and that the continued downward movement will cause thearms 14 t swing about their fulcrums 15 to apply molding pressure alongthe sides of the counter, which pressure will be increased as thedownward movement of the block 1S continues.

'lhe lower end of the levers 16 carry rollers 33 which are arranged toengage plates 34 carried by the inner ends of heads 35 mounted upon rods36 and backed up by springs 37 received in the chambers 38 of thecasings 26, the arrangement being substantially the same as that of thespring supported heads 24 heretofore described.

It will be noted that after the back of the divided mold 12 engages thecounter at the back of the mold 2, that the continued downward movementof the divided mold thereafter, has a tendency to cause the beveled endsof the arms 14 to swing farther inward greatly increasing the pressureexerted on the counter.

For the purpose of spreading the sections ol' the divided mold as it isretracted there are provided suitable coiled springs 39, the upper endsol' which are secured in the block 18, and the other ends to theswinging arms 14, so arranged that when the block or head 18 isretracted the springs 39 actto spread the arms 14 and to open thedivided mold.

It will be noted that by supporting the male mold in such manner that itmay yield slightly in a longitudinal direction or in the direction oftravel of the female mold, provision is made for the further movement ofthe female mold after it shall have closed around the counter on themale mold, such further downward movement causing the pivoted ends ofthe arms 14 to still further move inward the members of the divided moldto increase the pressure exerted on the counter, which pressure byreason of the compound pivotal action of the arms 14 and the levers 16will be substantially uniform along the entire surface of the counter.

Having described the construction and mode of operation of my inventionI claim as new and desire to secure by Letters Patent of tue UnitedStates:

1. A counter molding machine, having, in combination, a male mold, adivided female mold, arms carrying the members of the female mold andpivoted upon yielding sup ports, and yielding means for swinging saidarms upon their pivotal supports to close the female mold, substantiallyas described.

2. A counter molding machine, having, in

combination, a male mold, a divided female mold, pivoted arms supportingthe members of the female mold, pivoted levers supporting the arms, andmeans for actuating the levers and arms to close the female mold tocompress the blank, substantially as described.

3. A counter molding machine, having, in combination, a male mold, adivided female mold, pivoted arms for closing the members of the femalemold to compress the blank, pivoted levers connected with and actuatingthe arms and a reciprocating cross-head conneeted with and actuating thepivoted levers, substantially as described.

4. A counter molding machine, having, in combination, a male mold, adivided female mold, a reciprocating cross-head, a pair of leverspivoted to the cross-head, a pair of arms pivoted to the levers, and sup)orting the members of the divided female mo d, and yielding headsarranged to engage the free ends of the levers and arms, substantiallyas described.

1n testimony whereof 1 aflix my signature, in presence of two witnesses.
